Hi Ben. the issue here is that one of the AdGroupCriterion in your request needs to > have a case_value field that is not set
Sorry, but I thought I already tried that. Here are my protobuf messages and responses https://groups.google.com/d/msg/adwords-api/MKoKH8xVn-k/0q3JVm2nAgAJ (I don't have a lot of experiences with Google Groups so I hope that tрe link will be correct. In case it is not, this is the link to my 3rd message in this thread from August 20th) First 2 attempts in this message are errors which I get if I try to use `listing_custom_attribute` without `index` field. In the 3rd attempt I tried to use `listing_brand` field to match the Java examples from Bharani's messages. But still I've got an error. it's not very clear on how to do that in the Python In order to set empty protobuf message I just use these methods: SetInParent <https://developers.google.com/protocol-buffers/docs/reference/python/google.protobuf.message.Message-class.html#SetInParent> , ClearField <https://developers.google.com/protocol-buffers/docs/reference/python/google.protobuf.message.Message-class.html#ClearField> and the like. For example: ad_group_criterion.listing_group.case_value.listing_brand.SetInParent() This set of documentation > <https://developers.google.com/google-ads/api/docs/client-libs/python/empty-message-fields> > shows > how to set an empty message field in Python. > Just to be sure, if my string representations of protobuf messages (which I've been posting in previous messages) are correct, then the protobuf messages they were created from are also correct. Right? I mean, is it possible that I am somehow creating incorrect messages which are causing the error but still getting correct string representation? For example, I didn't use `CopyFrom` to create messages, I am creating them using this code: ad_group_criterion_operation = client.get_service(' AdGroupCriterionOperation', version=GADS_API_V) ad_group_criterion = ad_group_criterion_operation.create and then just filling value of the `ad_group_criterion` using standard protobuf methods.
